Unintended biases in machine learning (ML) models have the potential to introduce undue discrimination and exacerbate social inequalities. The research community has proposed various technical and qualitative methods intended to assist practitioners in assessing these biases. While frameworks for identifying risks of harm due to unintended biases have been proposed, they have not yet been operationalised into practical tools to assist industry practitioners.
In this paper, we link prior work on bias assessment methods to phases of a standard organisational risk management process (RMP), noting a gap in measures for helping practitioners identify bias-related risks. Targeting this gap, we introduce a bias identification methodology and questionnaire, illustrating its application through a real-world practitioner-led use case. We validate the need and usefulness of the questionnaire through a survey of industry practitioners, which provides insights into their practical requirements and preferences. Our results indicate that such an approach is helpful for proactively uncovering unexpected bias concerns, particularly where it is easy to integrate into existing processes, and facilitates communication with non-technical stakeholders.
Ultimately, effective end-to-end management of ML risks requires a more targeted identification of potential harm and its sources, so that appropriate mitigation strategies can be formulated. Towards this, our questionnaire provides a practical means to assist practitioners in identifying bias-related risks.
